Patent CA-2226358-A1 (CA)
Title: Modular brakes with replaceable friction pads
Inventor: MONTALVO EDWIN J
IPC: F16D66/02
Filed: 1998-02-11
Abstract: Generally trapezoid-shaped friction material pads can be used in conjunction with piston assemblies having torque collars with upstanding torque posts and with torque collars that have torque legs with inclined inner faces or shoulders to embrace side faces or shoulders of the pads.  A retainer clip cooperates with the torque legs to prevent unwanted radial movement of the pad.  A back plate of the pad has one or more tabs projecting beyond a wider base of the pad for facilitating pad removal.  Tabs on the pad for indicating that a worn friction pad is due for replacement are located beyond the wider base of the pad or within the friction material pad.  The friction pads are adapted for installation on module bases which include air ports on side surfaces and are constructed for interconnection that provides for air transfer between adjacent modules via the air ports.  A piston assembly for applying the friction pads in a braking operation includes an indexing mechanism to align and secure the friction pads to the piston assembly.

Title: Method and apparatus for delivering a cased glass stream
Inventor: SCOTT GARRETT LEE
IPC: C03B7/08
Filed: 1998-03-27
Abstract: Apparatus for forming a cased glass stream that includes at least one pair of aligned orifices coupled to sources of core and casing glass such that glass flows by gravity from the first and second sources through the aligned orifices to form a cased glass stream. The orifices are carried by an orifice housing mounted on a frame for movement into abutment seating engagement of the orifice housing against the core and casing glass delivery mechanisms.

Patent CA-2235216-A1 (CA)
Title: Embedded data link and protocol
Inventor: DALY CHRISTOPHER NEWTON DALY
IPC: H04L27/02
Filed: 1995-10-19
Abstract: A data link and protocol for a subcutaneous, tissue stimulating device. While stimulation is taking place, under control of pulses whose durations in a data frame determine the stimulation pulse widths, data is actually transmitted and processed for determining the parameters of the next stimulation. Thus transmission of data occurs simultaneously with stimulation. Data is represented by sequences which have more 1s than 0s, with each 1 being represented by a number of successive RF cycles and a single 0 by the absence of a number of RF cycles. In this way a duty cycle of 75 % can be achieved so that required power is transferred to the implant. Variations in link condition, e.g., degree of ringing, are accommodated by means of offset tuning the transcutaneous transmit and receive coils. This ensures that the oscillating signal in the receive circuit that persists during the transmission of a 0 becomes out-of-phase with the RF transmission that is received for the next 1. The signal induced in the receive coil with the transmission of a new 1 cancels the out-of-phase ringing in the receive coil due to the earlier transmission, thereby causing the oscillation's amplitude to fall below a detection level to ensure the detection of an earlier transmitted 0 during the time that the next 1 is transmitted. A  bit decoder is implemented that unambiguously recovers the number of is over a prescribed range of link transmission conditions. Also disclosed is a transmission system using variable-length frames representing both digital data and time-interval information, and a transmission system in which each frame has both analog and digital command information for selected utilisation circuits.

The apparatus comprises a growth zone in a vertically positioned tank, which growth zone is positioned below a nucleation zone. Via a delivery line the seed crystals are fed from the nucleation zone to the bottom end of the growth zone. In the growth zone the ice slurry slowly moves in a vertical direction at such a low velocity heavier particles are able to precipitate and to be discharged at the bottom end. Preferentially, the nucleation zone comprises a vacuum apparatus for effecting a reduction in pressure in the nucleation zone to between 10-4 and 7-10-3 bar. Using the apparatus according to the present invention it is possible for waste water and effluent to be concentrated in a simple manner, clogging of, for example, filters owing to the settling of solid particles being prevented.
Patent CA-2256248-A1 (CA)
Inventor: ZAMFES KOSTA
IPC: G01N33/28
Filed: 1998-12-16
Abstract: A method is provided for establishing the quality of the hydrocarbon in a formation while drilling is revealed using a ratio of two sensors applied to gases liberated from the drilling mud. Two rare earth gas sensors, one gas sensor (TG) outputs a signal proportional to the relative concentration of light hydrocarbons. The second gas sensor DTG outputs a decreasing signal with increased concentrations of heavy hydrocarbons and an increasing signal with increasing concentrations of light hydrocarbons. The ration of two signals provides an indication of the quality of the hydrocarbon. By applying drilling information to the TG analysis, values for the fraction of hydrocarbon in the pores of a formation are determinable. The TG  signals are normalized using a dilution factor for the volume of mud being analysed by the TG sensor compared to the overall circulation of mud, and a porosity factor determined for the drilled formation.

Title: Apparatus, program products and methods utilizing intelligent contact management
Inventor: BATES CARY LEE
IPC: G06F17/30
Filed: 1999-03-15
Abstract: Apparatus, program products, and methods implement various intelligent contact management operations to improve the productivity of users of electronic messaging systems and the like. To perform an intelligent name lookup, for example, a subset of the users in a contact database that meet a predetermined search criteria is identified, and a favored user is selected therefrom based upon a predetermined affinity criteria. Also, the automated addition of new entries to a contact database is supported by accumulating the number of contacts between a first user and a second user, with a new entry associated with the second user added to the contact database associated with the first user in response to the number of contacts between the first and second users exceeding a predetermined threshold. The automated addressing of electronic messages is also supported by determining, in response to a first user addressing an electronic message to a second user, whether the second user is a member of an electronic messaging group that defines a plurality of member users, and if so, to address the electronic message to at least one additional member user in the electronic messaging group. The automated creation of electronic messaging groups is also supported by addressing an electronic message to a plurality of recipient users in response to user input, and automatically creating a new electronic messaging group including the plurality of recipient users. Furthermore, the automated updating of electronic messaging groups is supported by addressing an electronic message to an electronic messaging group including a plurality of member users in response to user input, selectively updating an address list for the electronic message in response to user input, and selectively updating the electronic messaging group based upon the updates to the address list.
